Question

Concentrated aqueous sulphuric acid is 98% H₂SO₄ by mass and
has a density of 1.80 g mL⁻¹. Volume of acid required to make one litre
of 0.1M. H₂SO₄ solution is
(a) 16.65 mL (b) 22.20 mL
(c) 5.55 mL (d) 11.10 mL

Answer 1

Answer is option c

Answer 2

(c) 5.55 mL

Explanation:

density = 1.80 g/ml

mass = 98 g

volume = mass/density = 98/1.8

Molarity = Number of moles/ Volume

Number of moles = Given mass/ molar mass = 98/1.8

So Volume = Number of moles/ molarity = (98/1.8) / (9.8/0.1) = 0.1/1.8 = 0.005555 L

= 5.555 ml

Option C is the answer.
